References
引用
The References of a symbol is where
in the project the symbol is used.
符号的引用说的是符号在项目中那些地方使用。
For example, a variable can be
used/accessed by several code lines in several
code blocks, and
as an actual parameter to a function call or function block call,
or as a
比如说，变量可以在几个代码块的代码行中使用/访问，作为实际参数被功能或者功能块调用，或者作为参数被控制模块/单控制模块调用。变量也可以用于IO通道或者访问变量。

Search and Navigation dialog
图84. 搜索和导航对话框的引用部分
In the example in Figure 84, the
start symbol is used at two locations:
图84的例子，start符号用在两个地方
- function block OpenDoors, in Code code block of Diagram2. OpenDoors功能块，在Diagram2的叫做Code的代码块中
- in channel 3 of unit 1 at position 0 in
Controller_1.
Controller_1的位置0上单元1的3通道
It is possible to navigate to a
reference by double-clicking it, or by using the
context menu. The
enter key of the keyboard can also be used. The present editor is
shown
通过双击可以导航到引用位置，或者使用上下文菜单。也可以使用键盘的回车键。当前编辑器以突出显示的符号显示。
In
the References pane, the project name always appears as the
root. Communication Variables are the only symbols
that have references in
different
在引用窗格，项目名字总是出现在根部。通信变量是唯一在不同项目中具有引用的符号。
If
the communication variable that is being searched is present in
another project, the References pane displays this variable as part
of another project only if the other project also has been
downloaded from the same workstation as the current
project.
如果正在搜索的通信变量存在于另一个项目中，则仅当另一个项目也已从与当前项目相同的工作站下载时，“引用”窗格才会将此变量显示为另一个项目的一部分。
